testing out a headunit

Hey guys, I just got a new JVC headunit and want to test it out before the return date so I don't get screwed. Can I just hook it up to my stock speakers in the car, or do I have a chance of frying the headunit? I am dirt poor and I really cannot screw this up. Thanks. By the way one of the speakers is blown...will that mess up the headunit at all?

yea, I am not rich either. If the speaker is blown with a short, maybe ..... if it's blown with an open, no

Re: testing out a headunit

anyone know where or how I can test it out? What are the chances of damaging the headunit if I were to install new speakers?

Re: testing out a headunit

I don't think a blown speaker will do anything. You can't just wire it up and see if it works? I don't understand what you mean by "testing". Just hook it up, see that everything works, and then put your stock back in if you want.

Re: testing out a headunit

if you can unhook the blown speaker there would be little chance of damaging the hu. i just wouldn't crank it too high running stock speaks, or you may blow them too.

Re: testing out a headunit

then you would need to attach a speaker to each output to test the internal amp. you might want to test the rca preamps too.
